'The Vampire Diaries' Recap: The Luka Martin Roast

After Elijah's death, I thought it might be a while before The Vampire Diaries
killed another major character. How wrong I was, because in this
episode, two major characters are killed, a major secret is revealed and
a shocking return is sure to cause some trouble.

With Katherine back, she's up to her old tricks, but she also wants to
team up with the Salvatores to kill Klaus, which they understandably
have a hard time believing.
